ICE-MAKING- APPARATUS.

Specification of Letterslatent' P t nt 4 Application filed lfovember 8, 1919. Serial No. 336,559.] I

To all whom it may concern:

Be it known that I, ANsoN J. BENTLEY, a citizen of the United States, and, a resident of the city of Niles, county of Trumbull, and State of Ohio, have invented an Imrovement i11 Ice-l\1aking Apparatus, of which the following is a specification. I

This invention relates to apparatus employed incthe manufacture of artificialice and it particularly relates to the freezing cans which receive water to be frozen and which are placed in or neara freezing solution. u f v One of the. objects of this invention is to provide a fluid conductor to be assembled with the freezing can; the conductor, preferably a tube, will form aeonduit for the fluid, generally airunder pressure, to the bottom of the freezing can. This fluid after passing into the can will rise and thereby keep the impurities in the water agitated so that they will not be included in the ice.

Another and important object of this invention is to assemble the tube -with the freezing can so that the tubedoes not enter thecan to any substantial extent and is held against the side of the can so that it is not injured during the formation of the ice and the removal of the ice cake. I y

This invention. possesses many-other and advantageous features, some of which, together with the foregoing, will be set out more at lengthin the following description wherein will be outlined in full that form of the inventionwhich has been selected for illustration in the drawings accompanying and forming a part of the present specification. c V v The attached drawing which forms a part of this application illustrates one of the pre preferred embodiments of theinvention, wherein:

Figure 1 is a perspective view of the can.

Figure 2 is a section thereof taken below the reinforcing band at the top of the can.

. Figure 3 is a section taken on the line 3-3 of Figure 5. V

Figure 4 IS a section in partof one of the 7 sides, the base, and the conducting means,

showing one method of attaching the con ducting means or tube to the side, and

Figure 5 is a section in part of the base, of one of the sides, the tube, and one of the protecting members, shqwing an additional method of attaching the conducting means to the side.

I1'1jlC6 making apparatus, referring part cularly to the container for forming cakes of ice, there has been employed a means for conducting a fluid from the top of the can to the bottom thereof and allowing the exit of'the fluid into thewater to be congealed thereby keeping the impurities in thewater moving so that they will not be included in the resulting cake of ice. Several various means have been employed in order to conduit this fluid to the bottom of'the can. It is not advisable to have the conducting means or tube enter the freezing can but to have an opening in the side thereof through which the fluid maypass directlyiinto the water to be congealed. In the practical use of these ice freezing cans, it is advantageous to have a substantially smooth interior surface so that the ice will have a uniform shape and can beeasily removed from the can.

The invention herein disclosed and de scribed provides for the attachment of a conducting. means or tube in the opening in the side of a freezing can. The tube itself does not extend into the can in all in-v stances but it may extend therein for the purposes of forming a positive attachment but not to make a substantial projection in the can which would allow the formation of a shoulder in the ice cake which would render difficult the removal of the cake of ice from the can. 1

Referring to the figures, there is shown in T" I I i igure 1 the freezing can 1 having the base 2 and the reinforcing flange 3 at the top.

This flange may be an additional member or maybe an extension of the sides turned over upon themselves, A portion of a channel 4 formed in one of the sides is illustrated at I the top of the can and this channel receives the tube 5 which forms a conduit for the liquid from the top of the can to the lower part thereof. Protecting members 6' are provided to assist in maintaining the tube in position, if desired, andto protect it; These protecting members may be spot Welded into the lower part of the channel to receive the tube which forms the conduit, for the fl id. It is advantageous in apparatus of this character to have the fluid enter the cannear the bottom and since the can is set in a freezing solution it becomes, necessary to conduct .the fluid from the top of the can to the bottom and the tube employed may be any of the well-known designed pipes or tubes. The tube as'selected is illustrated herein a s'being circular. The top of the tube may be ta pered on its inner surface to receive a plugor there may be on its external surface near the top. thereof annular beads for assisting holding a flexible hose in positive con tact with the end of the tube, or any other well-known attaching means may beemployed. Preferably the tube should not enter the can as the formation of the ice would then, provide the formation of shoulders inthe ice which would prevent the easy removal of the ice cake. In the illustrations herein made, the freezing can is When a rectangular freezing can is employed, it may be advantageous to have the fluid pass. acrossthe longest diameter of the can and for this reason the tube is shown as being assembled in a channel formed in one of the narrower sides. A channel and a tube assembled therein may be employed in general contour of" the base and to be each or any of the sides ifdesired, or a channel without the tube may be formed in anyof? the sides.

The general formation of the base of the freezing can is partially shown in Fi ure,

4 wherein the edges of the base; are 0 -U- shape, having-the sides 7 and 8. The interior part of the base 9 is higher than the and are held therein byany holding means, as;

for instance, rivets 10'-illustrated in this figure. The lower end of the channel is shown as formed in aside 11.- Preferably, the channel is of. uniform depth and extends from the top of the side to the bottom at a, point just'ab'ove the interior portion 90f the base, and is then bent outwardi to'conform to the re ceived by the; U-shaped portion.

Anopening 12 is made in the side 11 for the reception of the fluid conducting tube, 5. In. this instance the end of the tube is bent and is received by the opening 12. If

desired, the end-of the tube may be tapered and the hole 12'reamed to-fit therewith, the object being to form a fluid" tight joint in a simple manner. Preferably thejoint between. the tube-and the can is solderednot only for the purpose of rendering the joint fluid tight but also to assist in holding the described above.

A modification of the method of attaching the tube to thefreezing can is shown in Figures 3 and 5. The method herein employed is, to; have the opening 12 of nonuniform diameter and tohave the end of the tube 5'tapered so that it. enters the opening 12 and the projecting part of the tube turned back against the inner part of the side 11 thereby causing the endof' the tube to be firmly held in contact with the side. The peaning of the end of the tube against the side is performed in such a manner as to. create the smallest shoulder possible on the interior surface of the side 11. and thereby preventing any substantial shoulder from' being formed in the; ice cake which would prevent the easy removal of the cake of ice.

It might not be necessary when using this method of attachment to employsolder and such an attachment would not be a substantial entrance of the tube into the int-erior of the freezing can.

It will be understood that the embodiment of the invention herein described and shown in the-accompanying drawings may be-variousl'y modified, and that the present inven: tion is susceptible of different embodiments. Insofar as such modifications and embodiments of theinvention come within the scope of the following claims they are considered to be within the scope of the invention. Y

I claim:

' A freezing can having a channel formed. 7

vertically in' one wallthereof, said channel being of identical 'crosssection from the top of the can to a point adjacent the base; when said channel is provided with an end wall contactingsubstantially with the base of the can near the edge thereof, anair tube provided with an integral elbow atone end for insertion in a hole formed in, the inner wall of the channel adjacent the lower" end thereof, said tube being fastened in said channel and extending from end to. end thereof" and being securely attached thereto at the lower endto form an air tight" conduit opening: to the interior ofthe-can, whereby air may be forced throughsai'd tube to agitate Water in said can during the freezing operation. I c

In testimony whereof, I have signed' my name to this specification this fifth day "off I November, 1919. r
